Key Findings

  • 01Higher heat treatment temperatures (up to 190°C) generally increased combustion temperature.
  • 02Impregnation with chemicals tended to increase smoke density while reducing combustion temperatures.
  • 03The highest flame source combustion temperature was observed in unimpregnated, heat-treated wood at 190°C.
  • 04The highest non-flame source combustion temperature was observed in wood impregnated with Timbercare-aqua and heat-treated at 170°C.
  • 05Smoke density generally decreased with increasing heat treatment temperature.

Application

Design takeaway

When specifying wood for applications with fire safety considerations, consider the impact of any proposed heat or chemical treatments on its combustion and smoke generation characteristics.

How to apply

When designing furniture, interior finishes, or structural elements using wood, consult material data that includes combustion properties after relevant treatments.

Project actions

  • 01When researching materials, look for data on how treatments affect their performance, not just the base material.
  • 02Consider fire safety regulations and smoke emission standards when selecting materials for your design project.

Method & Evidence

AimTo investigate the impact of heat treatment and eco-friendly impregnation on the combustion properties (flame and non-flame temperature, smoke density) of Hornbeam wood.
MethodExperimental testing
ProcedureWood specimens were impregnated with two different eco-friendly chemicals (Imersol-aqua and Timbercare-aqua) and then subjected to heat treatment at various temperatures (150°C, 170°C, 190°C) for a fixed duration (2 hours). Combustion properties were then measured using standardized tests (ASTM E 160-50).
ContextWood material processing and fire safety engineering

Variables

IV["Heat treatment temperature","Impregnation chemical type"]
DV["Combustion temperature (flame source)","Combustion temperature (without flame source)","Light intensity (smoke production)"]

Strengths & Limitations

Strengths

  • +Uses standardized testing methods for comparability.
  • +Investigates the combined effect of two common wood treatments.

Limitations

The specific chemicals and temperatures tested might not represent all available options. Real-world fire conditions are more complex than laboratory tests.

Reliability & validity

The use of standardized ASTM methods enhances the reliability and validity of the combustion property measurements. However, the limited sample size and specific wood species may affect generalizability.

Think critically

How might the observed changes in combustion properties influence the long-term durability and structural integrity of the wood in a fire scenario?

05

Design Principles

"Material treatments can significantly alter inherent performance properties, necessitating thorough evaluation for specific application requirements."

Understanding how treatments affect wood's combustion properties is crucial for selecting appropriate materials in applications where fire safety or smoke generation is a concern. This knowledge informs material selection for interior design, construction, and product development.

06

What This Means for Your Design

Heating wood and soaking it in special chemicals changes how easily it burns and how much smoke it makes.

How to use in your project

  • 1.Use this research to justify material choices based on fire safety performance, or to explain unexpected results in your own material testing.

Quick Cite

Paragraph starter

The research by Perçin and Atar (2018) demonstrates that heat treatment and impregnation of wood materials significantly alter their combustion properties. Specifically, higher heat treatment temperatures increased combustion temperatures, while impregnation chemicals tended to increase smoke density, highlighting the importance of considering treatment effects when selecting wood for fire-sensitive applications.
